Hi everybody, recently I have made complete iteration from fresh PROD 11i instance to R12.1.1 with database 11.2.0.2

I have used VMware for this iteration, the following step involved to achieve this upgrade from 11i to R12.1.1

OS – OEL 4.6
Memory 3GB
Instance 11i CU2
Database 9.2.0.6

My VMware installation has been running on P5 processor with 4GB memory under Windows 7 (64 bits) machine.
Before starting this iteration, I have enabled multi-org. So please follow multi-org enabled procedure prior to this step.

The following steps performed successfully to complete this hectic upgrade from 11i instance to R12.1.1

•Upgrade 9.2.0.6 to 10.2.0.4

–Patches applied before 10g upgrade are 5478710, 4676589, 4653225

–Changed some of the OS kernel parameters

–Created new oracle home directory

–Installed 10gR1 (software only)

–Installed 10g patch set 3 (10.2.0.4)

•Configuration section for 10g

–Created nls/data/9idata

–Run the script cr9idata.pl

–Copied environment file from 9i home to 10g home and made changes to reflect the directory structure of 10g home

–Copied TNS_ADMIN directory from 9i to 10 home and made changes according to new home

I need your expertise advise. My client is having Dbtier and AppsTier on windows 2003(32 bit) server. Now we are planning to move to 12.1.3 on windows 2008R2(64 bit). DB from 10.2.0.3 to 11gR2. I am going through metlaink notes. What I uderstood is as RapidInstall 12.1.1 cannot be directly done on 64 bit. they are suggesting to upgrade teh windows 2003(32 bit) to 12.1.1 and then do rapid clone to 2008R2(64bit). My doubt here is...when to upgrade the DB. as 11gR2 installation available on 64bit.. which is the right step. first upgrade it to 11gR2 at 32 bit and then migrate it to 64bit and apply OLAP sizingor secondly..install 11gR2(64bit) installation on Windows2008R2(64 bit)..
